Product Overview
YT-908 is a stable and reliable 8-channel intelligent detection module for switch status, providing acquisition and conversion functions from 8-channel switch input to RS485 signal output. Remote important equipment on/off and status collection can be achieved through RS485. The communication protocol adopts Modbus RTU to achieve the fastest industrial transmission. The RS485 interface effectively implements photoelectric isolation technology, effectively suppressing lightning, lightning strikes, ESD, and common ground interference. Provide a five-year warranty service.
